How to scroll scanline image data from the left to the right

You want to scroll the image or move its data?

I need to scroll the image itself. The image data is received over a socket. The image data is just an array with the pixel values and dimensions, as 16bit bmp. I will get probably 10 lines or so on each payload and i need to append this data to a qimage and begin scrolling it onto the screen as the data is recieved from the left side, once the image is completely built i need it to continue and move across the display till it goes off the display on the right side. Im not sure if qanimation will look smooth enough, and i cant have it flickering but still needs to be somewhat fast. Also wondering if bitblt in a paintevent should be used for this. Thanks
